Implication

Experimental study demonstrates reversible optical beam steering via light-actuated liquid crystal elastomer fibres, suggesting a simpler alternative to complex telecommunication switching systems.

Key Points

To develop a simplified, remotely driven optical beam-steering mechanism using liquid crystal elastomer fibres.
Fabricated liquid crystal elastomer (LCE) fibres capable of contracting and rotating in response to selective light irradiation.
Mounted a mirror onto an LCE fibre to construct an optically driven beam-steering device controlled by adjusting irradiation power.
Achieved full in-plane directional deflection of a laser probe beam by precisely controlling the fibre and mirror rotation angle.
Induced controllable rotations exceeding one complete revolution around the fibre axis via light-stimulus power modulation.
Observed complete reversibility of the mechanical rotation and beam deflection upon removal of the light stimulus.
